Smooth Loading Operation

Two return hoses improve

hydraulic performance. In the arm

out function, a portion of the oil is

returned directly to the tank

providing smooth operation.

Boom floats upward, reducing lifting of machine front. This facilitates gathering blasted rockand scraping down operations.

Boom pushing force isincreased, ditch digging andbox digging operation on hardground are improved.

Two-mode Setting for Boom

Smooth mode provides easy operation for gathering blasted

rock or scraping down operation. When maximum digging

force is needed, switch to Power mode for more effective

excavating.

PRODUCTIVITY & ECOLOGY FEATURES

Environment-friendly Clean Engine

The PC400-8 gets its exceptional power and work capacity

from a Komatsu SAA6D125E-5 engine. Output is 257 kW

345 HP, providing increased hydraulic power and improved

fuel efficiency.

Komatsu SAA6D125E-5 engine meets EPA Tier 3 and EU

Stage 3A emission regulations with NOx emission reduced

by 40%.

The SAA6D125E-5 engine adopts the electronically con-

trolled Heavy Duty HPCR* fuel injection system and cooled

EGR system with electronically controlled bypass-assist type

venturi.

*HPCR : High Pressure Common Rail

Low Operation Noise

Enables a low noise operation using the low-noise engine

and methods to cut noise at source. Ambient noise meets

the EU Stage 2 noise regulation.

Komatsu Technology

Komatsu develops and produces all major

components, such as engines, electronics

and hydraulic components, in house.

With this “Komatsu Technology,” and adding

customer feedback, Komatsu is achieving

great advancements in technology.

To achieve both high levels of productivity

and economical performance, Komatsu has

developed the main components with a total

control system. The result is a new genera-

tion of high performance and environment

friendly excavators.

Working Modes Selectable

Two established work modes are further improved.

P mode – Power or

work priority mode has

low fuel consumption,

but fast equipment

speed and maximum

production and power

are maintained.

E mode – Economy or

fuel priority mode

further reduces fuel

consumption, but main-

tains the P-mode-like working equipment speed for light duty

work.

You can select Power or Economy modes using a one-touch

operation on the monitor panel depending on workloads.

Idling Caution

To prevent unnecessary

fuel consumption, an idling

caution is displayed on the

monitor, if the engine idles

for 5 minutes or more.

Eco-gauge that Assists Energy-saving Operations

Equipped with the Eco-gauge that can be recognized at a

glance on the right of the multi-function color monitor for

environment-friendly

energy-saving opera-

tions. Allows focus on

operation in the green

range with reduced CO2

emissions and efficient

fuel consumption.

Thermal and Fan Guards

Thermal and fan guards are

placed around high-

temperature parts of the

engine and fan drive.

WORKING ENVIRONMENT

Large Serrated Steps Large Hand Rail


Lock Lever

Locks the hydraulic

pressure to prevent

unintentional move-

ment. Neutral start

function only allows

machine to be start-

ed in lock position.

Low Cab Noise

The newly-designed cab is highly rigid

and has excellent sound absorption

ability. Thorough improvement of noise

source reduction and use of low noise

engine, hydraulic equipment, and air

conditioner allows this machine to

generate a low level of noise.

Low Vibration with Cab DamperMounting

PC400-8 uses viscous damper mount-

ing for cab that incorporates longer

stroke and the addition of a spring.

The new cab damper mounting

combined with high rigidity deck aids

vibration reduction at operator seat.

Wide Newly-designed Cab

Newly-designed wide spacious cab

includes seat with reclining backrest.

The seat height and longitudinal incli-

nation are easily adjusted using a pull-

up lever. You can set the appropriate

operational posture of armrest together

with the console.

Reclining the seat further enables you

to place it into the fully flat state with

the headrest attached.

Pressurized Cab

Optional air conditioner, air filter and a

higher internal air pressure (+6.0 mm

Aq +0.2"Aq) prevent external dust

from entering the cab.

Automatic Air Conditioner(optional)

Enables you

to easily and

precisely set

cab atmos-

phere with

the instru-

ments on the large LCD.

The bi-level control function keeps the

operator's head and feet cool and

warm respectively. This improved air

flow function keeps the inside of the

cab comfortable throughout the year.

Defroster function keeps front glass

clear.

Safety Features

Rubber

Silicon Oil

Spring

Anti-slip Plates

Highly durable anti-slip

plates maintain superior

traction performance for

the long term.

Cab Dedicated to Hydraulic Excavator

The cab is designed specifically for hydraulic excavators and

gains reinforced strength from the pipe-structured cab frame-

work. The cab framework provides the high durability and

impact resistance with very high impact absorbency. The

seat belt keeps the operator in the safety of the cab during a

rollover.

Easy Maintenance

Large Capacity Air Cleaner

Large capacity air cleaner is

comparable to that of larger machines.

The larger air cleaner can extend air

cleaner life during long-term operation

and prevents early clogging and

resulting

power

decrease.

Reliability is

improved by a

new seal

design.

Long Work Equipment GreasingInterval (optional)

High quality BMRC bushings and resin

shims are optionally available for work

equipment pins excluding bucket,

extending greasing interval to 500 hours.

Large Fuel Tank Capacity

Large fuel tank capacity extends

operating hours before refueling. Fuel

tank is treated for rust prevention and

improved corrosion resistance.

High Pressure In-line Filter

In-line filters are provided at outlet port

(pressure side) of each pump to

protect hydraulic system contamination.

filter are mounted on same side to

improve accessibility. Fuel drain valve

are remotely mounted to improve

accessibility.

Fuel Drain Valve

Equipped withFuel Pre-filter(with Water Separator)

Removes water and

contaminants in the

fuel to prevent fuel

problems.

Easy Radiator Cleaning

Since radiator and oil cooler

are arranged side-by-side, it

is easy to clean, remove

and install them.
